Hin and Mounfain Roads
Driving on steep hills or mountains is
dif€erent fram driving in flat or rolling
terrain. If you drive regularly in steep
country,
or if you're planning to visit
there, here are -some tips that can make
your trips safer and.more enjoyable.
Keep your vehicle in good shape. Check
all fluid levels and also the brakes, tires,
cooling system and transmission. These
parts can work hard on mountain roads.
Know how to go down hills. The most
important thing to how is this: Let
your engine do. some of the slowing
'down. Don't make your brakes do it
all. Shift to a lower gear when you go
down .a steep or long hill. That way,
you will slow down without excessive
use of your brake-s.
Know how to go uphill. You may
want to shift dawn to a lower gear.
The lower gems help cool your engine
and transmission, and you can clin-ib
the *f hiU better.
Stay in your own lane when driving
on two-lane roads in hills or
mountains. Don't swing wide .or cut-
across. the .center of the road. Drive at
speeds that-let-you stay 'in your own
lae. That way, you won't be
surprised by,a vehicle- coming toward
you
in the same lane.
* It takes longer to pass another vehicle-
when you're going uphill. You'll want
to leave extra room to pass. If a
vehicle is passing you and doesn't
have enough room, slow down to
make it easier for the other vehicle to
get by.
